When you press , you can choose whether to compute the statistics for all entries, or only any selected (highlighted) entries, or only those between two initial characters e.g. between A and D, or indeed to use your own specified words only.

If you wish to select only a few items for MI calculation, you can mark them first (with ). Or you can always do part of the list (eg. A to D) and later merge your mutual-information list with another (E to H).

Alternatively you may choose to use only items from a plain text file constructed using the same syntax as a match-list file., or to use all items except ones from your plain text file.

omit any containing # will cut out numbers, and omit if word1=word2 is there because you might find that GOOD is related to GOOD if there are lots of cases where these 2 are found near each other.

show pairs both ways allows you to locate all the pairs more easily because it doubles up the list. For example, suppose we have a pair of words such as HEAVEN and EARTH. This will normally enter the list only in one order, let us say HEAVEN as word 1 and EARTH as word 2. If you're looking at all the words in the Word 1 column, you will not find EARTH. If you want to be able to see the pair as both HEAVEN - EARTH and EARTH - HEAVEN, select show pairs both ways. Here we can see this with DUST and WITH

to right only: if this is checked, possible relations are computed to the right of the node only. That is, when considering DUST, say, cases of WITH to the right will be noticed but cases where WITH is to the left of DUST would get ignored.

Here, the number of texts goes down to 5 from 9, MI score is lower, etc, because the process looks only to the right. (In the case of a right-to-left language like Arabic, the processing is still of the words following the node word.)

recompute token count allows you to get the number of tokens counted again e.g. after items have been edited or deleted.

Set the maximum frequency, for example, to 0.5% to cut out words whose frequency is greater than that; a minimum frequency of 5 means that no word of frequency 4 or less in the index will be visible in the relationship results.

(Above 0.5% in the case of the BNC would mean ignoring about 20 of the top frequency words, such as WITH, HE, YOU.  Above 0.1% would cut about 100 words including GET, BACK, BECAUSE.)

stop at allows you to ignore potential relationships e.g. across sentence boundaries. It has to do with whether breaks such as punctuation or sentence breaks determine that one word cannot be related to another

span refers to the collocation horizon. A span of 5 means, for example, from the node word forward to R4 position, inclusive.

The other minima can be adjusted for each type of statistic.
